Hydroxycut Lean X Next Gen Review – Stim-Free, Funky-Fresh Fat Loss Stack

Hydroxycut Lean X Next Gen Review

Hydroxycut Lean X Next Gen is a stimulant-free fat burner that is the latest offering in MuscleTech’s legendary line of weight loss supplements. Like other Hydroxycut formulas, it is a unique stack that combines tried-and-true fat burners with a couple of unusual exotics — leveraging some out-of-the-box formulation strategies to remain stimulant-free. But does Lean X Next Gen truly deliver fat loss support without the jitters? Let’s find out in this Hydroxycut Lean X Next Gen review.

About Hydroxycut Lean X Next Gen

MuscleTech® Hydroxycut® Lean X Next Gen is billed as a powerful, non-stimulant fat loss supplement that leverages potent botanicals that deliver fat burning activity without jitters, overstimulation or related side effects. Formula notes:

  • C. canephora robusta. Also known as green coffee bean, this is Hydroxycut Lean X Next Gen’s driving force. They use a high-quality extract, standardized to its active CGA compounds.
  • Unusual stim-free stack. Things can get weird when fat-loss supplements venture outside the reliable effects of stimulant-driven formulas.
  • Quality botanicals. Bioperine® black pepper extract, standardized rhodiola and standardized green coffee bean extract are all good lookin’, top-shelf, high-quality forms.

Lean X Next Gen delivers science-backed, non-stimulant fat burners that WORK, and obscure (but sexy-sounding) botanicals that don’t.

If you are familiar with fat loss products, then you probably already know the MuscleTech® Lab Series Hydroxycut® drill: they take some evidence backed fat burners, mixed in a couple of obscure botanical exotics, and give the product a sexy name. Let’s take a look at what these ingredients and how they are combined.

Non-Stimulant Support Matrix

Acetyl L-Carnitine HCL, 500 mg

This form of l-carnitine is sometimes included in fat burner supplements because it plays a supportive role in fat metabolism. In particular, it is suggested to help with the transport of fatty acids into cells powerhouse mitochondria, where they are converted into ATP energy. For that same reason, l-carnitine is sometimes included in energy booster supplements.

  • Because of its role in fatty acid transport, l-carnitine is theorized to be beneficial during low-carb or keto diet programs, where the body is encouraged to burn its stored energy reserves (also known as “love handles” and various other euphemisms) first and foremost.

L-carnitine does not have a ton of evidence as a direct fat burner nutrient, however, its bioactivities are fundamental to the fat metabolism process. We like it as a stimulant-free fat burner ingredient for its cell energy metabolism-optimizing activity.

Choline Bitartrate, 100 mg

Choline appears in some fat loss supplements, as well as some pre-workout supplements, even though it is most accurately described as a nootropic brain booster. It has a number of different bioactivities, but the one most relevant to weight loss appears to be its support for acetylcholine, a stimulatory neurotransmitter that is associated with robust metabolic function.

You can’t really call choline a fat burner, however it may bring some cognitive and physical performance-enhancing benefits that help to maintain focus while dieting and improve training intensity for better weight loss results.

Hey Hydroxycut… Dill is for PICKLES, not fat burners.

Dill Extract, 50 mg

This is a great example of how Hydroxycut throws in some obscure exotics that, at times, are hard to justify in a fat loss supplement. Look at how Muscletech explains Dill’s presence in Hydroxycut Lean X Next Gen:

  • “The seed of Anethum graveolens have been used traditionally for a long time.”

Could they be any more vague? The truth is, there is very little evidence supporting dill as a beneficial herb for any health application. Some very early research suggests that Dale may have antioxidant, inflammation modulating, and blood sugar effects, but those connections are way too loose and weak for our tastes.

Lion’s Mane, 50 mg

Like choline, lion’s mane mushroom is most often used as a nootropic ingredient.

Lion’s mane is most famous for helping to increase nerve growth factor, which in turn supports overall brain health and has been linked in some research studies to improvements in mood and memory. Again, this is an exotic ingredient that sounds great, but has no connection to any fat loss mechanisms.

BioPerine®, 5mg

Now we are getting somewhere. Patented BioPerine® black pepper extract is one of our favorite overall ingredients to include in fat burner supplements. The main reason is, black pepper extract helps to optimize nutrient absorption and bioavailability, which means more of the ingredients you swallow in a capsule will actually reach your bloodstream to exert fat-burning activities.

The other reason is, black pepper extract on its own supplies some thermogenic activity. It helps to raise body heat, thereby enhancing your calorie burning efforts, whatever they may be.

Weight Loss Plus Complex

C. canephora robusta (standardized for 45% Chlorogenic Acids), 200mg

MuscleTech seems to be putting a good deal of emphasis on this ingredient, also known as green coffee bean, in its new Hydroxycut products, including:

MuscleTech includes C. canephora robusta in a couple of its pre-workout supplements too. Clearly they have a lot of faith in it as a fat burner ingredient.

Green coffee bean extract has been one of the leading fat burners for a few years now.

It has a decent amount of research suggesting fat loss benefits, although the mechanisms by which it works are not yet entirely clear.

  • Science has identified green coffee beans’ active fat-loss ingredients as Chlorogenic Acids (CGAs).

CGAs are believed to work by a combination of effects that include balancing blood sugar, enhancing glucose metabolism and blocking fat storage. Again, these bioactivities are not proven, however, green coffee bean extract has shown potential for helping with weight loss in human studies. Hydroxycut Lean X Next Gen cites two of these studies:

  1. Green coffee bean extract supplement taken for 60 days was associated with 10.95 pounds of weight loss, versus 5.4 pounds in the placebo group
  2. Study subjects taking green coffee bean extract for 8 weeks lost about 3.7 pounds, versus 1.25 pounds lost in the placebo group

In both of these studies, participants also followed a low-calorie diet. In addition, both of these studies were performed on a premium branded green coffee bean extract called Svetol. That means that Hydroxycut Lean X Next Gen is using an excellent, clinically studied form of the unroasted coffee beans.

Unlike your favorite coffee beans, Green Coffee Beans are unroasted, which preserves their active chlorogenic acids. MuscleTech seems to be featuring green coffee beans in a lot of their products.

Rhodiola extract, 50 mg

Rhodiola is a golden root herb associated with traditional Russian herbalism. It is most famous as an adaptogen – that means that it helps the body to adapt to various stressors more effectively. This stress-reducing effect is prized for enhancing both physical and mental performance.

Rhodiola is a great ingredient for supercharging training and exercise to new heights of intensity, thereby helping with weight loss.

As an actual fat-burner, however, Rhodiola has a very little evidence. Some early exploratory research suggested that Rhodiola’s energizing effects might play a role in regulating the formation of fat cells. But that research is weak.

In this Hydroxycut Lean X Next Gen review, we speculate that the formula includes Rhodiola rosea as a multi-tasking herb to support other aspects of wellness during your diet. In particular we think Rhodiola might be useful here because it:

  • Reduces stress. Dieting is stressful, and stress releases the hormone cortisol, which in turn is associated with weight gain
  • Enhances physical performance. Rhodiola can help you burn more calories by boosting strength and endurance
  • Acts as a nootropic. It may help with focus and concentration, helping you so achieve greater workout intensity and mood balance during dieting

Keep in mind that Hydroxycut Lean X Next Gen doesn’t make any of these claims, and neither are we – we are merely trying to theorize on how Rhodiola might help with the overall goals of this particular fat burner supplement.

Ophiopogon Extract, supplying polysaccharides, 50mg

Ophio-whaaaaat? Also known as Dragon’s beard, this Asian herb has long been used in traditional wellness practices. Very early animal research suggests that it might play a role in blood sugar in fat storage, which could explain why Hydroxycut Lean X Next Gen includes this obscure exotic.

  • In the opinion of Best5 Supplements, however, any evidence behind this herb is so superficial that it is highly unlikely it adds any fat burning support to this formula.

Cayenne pepper, 5 mg

Hydroxycut Lean X Next Gen redeems itself with this last ingredient. Cayenne pepper is one of our favorite fat burner ingredients. It is safe, natural, research backed and it works.

Specifically, various animal and human research studies have suggested that Cayenne’s active ingredient, capsaicin, might work by:

  1. Increasing thermogenesis, which raises body heat so you burn calories more efficiently
  2. Regulating fat oxidation, potentially helping the body to burn off its fat reserves as a priority

The 5 mg is a low dosage and the ingredient form is plain, which might limit the efficacy of this otherwise outstanding fat burner ingredient. For reference, check out another fat-loss formula that includes 25 mg of cayenne as Capsimax, which is the good stuff.

Formula Analysis

Hydroxycut Lean X Next Gen boldly announces that it is a “never-before-scene combination of powerful ingredients!”

You can say that again, Hydroxycut Lean X Next Gen.

The first thing that sticks out to us as we evaluate the formula in this Hydroxycut Lean X Next Gen review is that some of these ingredients just don’t belong.

It’s that classic Hydroxycut formulation strategy: sometimes the unusual exotics that they include make sense. But in this case… not so much. The Dill and Ophiopogon are certainly novel inclusions, but we highly doubt they bring anything to the table.

Choline and Lion’s Mane are better known ingredients. Lion’s Mane in particular is trending as a nootropic. However, neither one is a fat burner ingredient, and only the choline seems to have a place in any kind of formula for weight loss.

Specifically, choline’s support for the stimulatory neurotransmitter acetylcholine seems to make sense in a fat loss formula that is free of caffeine or other stimulants. In theory, acetylcholine support could help ramp up metabolism for similar effects without relying on caffeine.

However, the 100 mg dosage here is a little low; consider that another fat-burner, Trans4orm, supplies 200 mg of the same ingredient.

And 50 mg of Lion’s Mane seems unlikely to do anything, considering that a our top-rated mental performance-enhancing nootropic supplies 500 mg of the mushroom, 10X more.

Despite its puzzling formula choices, Hydroxycut Lean X Next Gen shows some skillful formulation strategies that we do appreciate.

Specifically, we salute MuscleTech for bringing a fresh new strategy to stimulant-free fat burner supplement design. L-carnitine seems like a great choice for this approach, because it helps to promote fat burning on a cellular level, right down to the cells’ powerhouse mitochondria.

Green coffee bean extract is another well-regarded fat loss ingredient that seems to work pretty well in non-stimulatory pathways.

  • For example, rather than revving up your engine into the red zone like an intense stimulant formula, green coffee bean extract may help to keep your blood sugar balance.

It’s not nearly as sexy, sensory or tangible as what you would experience with the super stimulating formula. However, blood sugar is closely related to appetite and fat storage, which could be just as significant as metabolic rate to your ultimate weight loss success.

Rhodiola is a great addition to this formula, as well. Although it is not a classic fat burner, it is a legendary performance enhancer. In addition, its anti-cortisol effects might just be on to something in terms of weight control, since high stress and subsequent cortisol spikes are associated with obesity.

Bioperine black pepper extract is the cherry on top. Bioperine is a premium brand of black pepper, extensively studied and standardized to 95% piperine, which is the active ingredient associated with both its nutrient absorption and thermogenic benefits. In general, black pepper’s dual-powered activities seem like a great addition to any fat loss formula, at least in our opinion. Including it here shows that there is sophistication in Hydroxycut Lean X Next Gen’s formula design.

Hydroxycut Lean X Next Gen Benefits

MuscleTech makes hardly any claims about what benefits one might expect to get by taking Hydroxycut Lean X Next Gen. They do, however, feature the green coffee bean extract as the driving force behind this formula. They seem to be using a branded form of green coffee bean extract that has demonstrated benefits in clinical research.

  • Specifically, the green coffee bean extract in Hydroxycut Lean X Next Gen has been shown in research to help people lose more weight overall due to a combination of blood sugar balancing and fat metabolism benefits.

Cayenne pepper and Bioperine black pepper will add to this fat burning activity, further encouraging weight loss.

The other ingredients are more challenging to crystallize into benefits. However, we think the formulas Rhodiola rosea, l-Carnitine and choline may add some extra support for physical performance, training intensity, mental focus and cell energy efficiency – all of which might help to indirectly support your fat loss program.

Who Takes It?

Anybody can take this formulation. It is a non-stimulant fat burner, so may be most popular among people who are sensitive to caffeine but still want some powerful thermogenic activity in their diet pill. In addition, Hydroxycut Lean X Next Gen might appeal to athletes and fitness buffs who would rather get there caffeine fix from a stimulant-driven pre-workout supplement. For people like this, stacking a caffeinated fat loss supplement on top of a caffeinated pre-workout supplement on top of coffee in an energy drink is generally not the best idea.

Any Side Effects?

As a non-stimulant weight loss formula, Hydroxycut Lean X Next Gen is designed to eliminate many of the common side effects that are associated with caffeine and other stimulating products. You know the ones. Jitters, aggression, nervousness, sleep problems. We are pretty confident that Hydroxycut Lean X Next Gen completely eliminates any stimulant -related side effect concerns. However, it is worth noting that this formula supplies cayenne pepper as a plain powder, which is sometimes associated with “burning stomach” sensation side effects.

Hydroxycut Lean X Next Gen Review Summary


  • Novel combination. Muscletech is right: We’ve never seen this combination of ingredients in any supplement before.
  • Honest label.. All ingredient dosages are shown, which is especially important when dealing with exotic fat burner combinations.
  • Unique formulation. Not all ingredients hit the mark, but those that do form a sensible stim-free fat loss stack.
  • Some Quality ingredients. Again not all the ingredients are high quality, but they get points for Bioperine, standardized green coffee bean and standardized rhodiola.


  • Some ingredients completely miss the target. Some exotics in Lean X Next Gen are really hard to justify in a weight loss formula, with very little research supporting them in this capacity.

Pricing and Where to Buy

  • Pricing not yet known. This is an advance Hydroxycut Lean X Next Gen review, published ahead of its official launch date. We will update this review as soon as a price for this supplement is set.
  • Like other Hydroxycut products, we anticipate that Lean X Next Gen will be widely available at Target, Amazon, Walgreens, Walmart, Target, Vitamin Shoppe other major retailers both online and in real life.

Final Word on Hydroxycut Lean X Next Gen

Hydroxycut Lean X Next Gen takes an ambitious approach to non-stimulant fat loss supplement design. Some ingredients are wacky, but that tends to be the name of the game when manufacturers are trying to come up with the next big stimulant-free fat loss product. Stimulant-driven products are more reliable; stim-free versions must often rely on experimentation.

In conclusion of this Hydroxycut Lean X Next Gen review, we suggest that the formula fails with its “wildcard” exotic ingredients, but its primary ingredients — Green coffee bean, ALCAR, Rhodiola, Cayenne and Black Pepper — are effective enough to make this nonstim fat-burner stack worth a try.

Ultimately this is a middle-of-the-road fat burner: Not the best Hydroxycut formula for weight loss (some are outstanding), and nowhere near our top-rated fat burner supplements overall.
